Interestingly, in volume 2, chapter 35, of Common Grace, Kuyper explains this formula as the cornerstone of his critique of the concept of the national church, which—because it sees itself as coterminous with the Christian gospel—is compelled to place under the aegis of the church as institution any cultural activity that is to be transformed by the gospel. Activities like science, art, education, politics, economics, etc. In short, because it fails to distinguish church from nation, the national church ends up incorporating the world into the church.
